Quick reminder that starting September 2026, a silent update, nonconsensually pushed by Google, will block every Android app whose developer hasn't registered with Google, signed their contract, paid up, and handed over government ID: https://www.theregister.com/software/2025/10/29/keep-android-open-movement-fights-google-dev-requirement/1470903

Addition:

Several of these OSes, including Sailfish, FuriOS, Mobian, and postmarketOS are all pure Linux OSs. They're not derived from Android, but they can all run an Android VM or container, and so allow you to install and use Android apps.
